关于reactjs的基础问题

Question

reactjs现在又更新了，没有了JSXTransform那个文件，换了个。我现在按照他的弄，为什么什么都没有，还报错。

 <div id="app"></div>

<script src="bower_components/react/react.js"></script>
    <script src="bower_components/react/react-dom.js"></script>
    <script>
        var React = require('react');
        var ReactDOM = require('react-dom');
        var MyComponent = React.createClass({
            render: function () {
                return <div> Hello World </div>;
            }
        });

        ReactDOM.render( < MyComponent / > , document.getElementById('app'));
    </script>
